Superior Density SiC Lumps
Product Introduction
High-purity Silicon Carbide Lumps (90%+) are efficient metallurgical auxiliaries that replace part of Ferro Silicon and Graphite. Our product is refined at high temperatures with a dense crystal structure and strong thermal shock resistance. Compared to ordinary Ferro Silicon, it significantly reduces inclusions in molten steel and improves the toughness and fatigue strength of steel. With stable composition and low impurities, our SiC Lumps are ideal for long-term consumption in steel mills and foundries.
Chemical Composition
Product Advantages
Cost Reduction: 1 MT of SiC Lumps can replace 1.3 MT of Ferro Silicon, significantly reducing deoxidation costs.
High Purity: Made from premium petroleum coke and quartz sand, extremely low S & P content to protect the furnace lining.
High Melting Point: Mohs hardness 9.2, melting point up to 2700°C, extending refractory life.
Uniform Size: Strictly sieved to avoid oversized or fine particles, ensuring smooth feeding without clogging.
Applications & Cases
Steel Deoxidation: Used in converter/EAF steelmaking to rapidly remove oxygen, reduce slag inclusions, and improve surface quality. (Case: Supplied a Vietnamese steel mill for 8 months, helping reduce deoxidation cost per ton by ~7%.)
Cast Iron Carburizing: Used as a carburizer and inoculant in gray/ductile iron to improve graphite morphology and eliminate chill.
Refractories: Used for ladle slide gates, stoppers, and high-temp furnace linings to resist steel erosion.
